5h 15min, apr 25, 1953 y - DNA structure revealed
Description:
On April 25, James D Watson and Francis Crick, two Cambridge University scientists, describe the structure of a chemical called deoxyribonucleic acid in Nature magazine.
DNA is the material that makes up genes, which pass hereditary characteristics from parent to child. Crick and Watson begin their article:
"We wish to suggest a structure for the salt of deoxyribonucleic acid (DNA). This structure has novel features which are of considerable biological interest."
Knowing the structure of DNA allowed the study of disease caused by defective genes.
